How good will this speaker sound?

[Gary L]

I am pretty sure this is a mighty fine speaker!

I am also pretty sure I would want some personal protection if I stick a pair of them in my 18 X 22 Living Room.

Without many bodies to soften the blow stuff like this is just overkill IMHO!

Dkalsi, I've got similar vintage K-horns and have had a grossly similar
setup (ported, short horn woofer, big horn mid+) in the living room
(open two story, ... lots of space). While the A7-like system was fun
and entertaining (and later tweaked with subs and slot tweeters), it
eventually grew tiresome.... indoors. Outdoors they crank .
I still like to listen to the K-horns (caps replaced, but no ALK mods)
now and then. I don't have a similar urge for the other system.

My 2 cents anyway. -grumpy

Hee, hee. Grumpy's got a pair similar to those, too, Gary.

With some minor reconfiguration, they could sound mighty nice in your living room.

[The aesthetic might even grow on you.... ]

That is the point here! "dkalsi" is looking at a pair of what appear to be stock A7s and asking how they will compare to his already highly moded Khorns.

I think they could be very nice if he puts similar upgrades and mods into the A7s as he did with the Ks. He will still need to get past the Utility appearance and size issues but A7s can certainly be made to sound quite nice in a living room as you have already pointed out.

I just think it is much easier and less expensive to start out with a speaker model that has it's roots in home use unless you happen to fall into some exceptional deal or have an appreciation for the type of sound stage these behemouths can provide.

BTW, The A7's would be a nice project for us die hard tweekers for sure and I would love to hear dkalsi report how it turns out as long as he is willing to make the appropriate mods! I almost bought those JBLs to do exactly that but dollars and sense turned me away.

What people are looking for does not define the standard. Generally speaking, however, that would be flat response, anyway.

Google is failing me today re: DIN 45500; I'd like to know what it actually says.

True.......

google failed me yesterday as well....

In any case, if "No noticeable emphasis or de-emphasis of any frequency" or "Faithful to the original master recording" is the definition, VOTT most certainly does not qualify as Hi-Fi unless "fixed."

You're gonna have to remind me what D31050M is.

With respect to Paragon, I'm in enough trouble with that already.

[I don't know how it actually measures....]

it's the double 15", exponential corner horn with the potato masher?
top right corner of the 1952 catalog.....

I hear you about the Paragon, I've never heard one either,

but thought that example may get my point across that all Hi-Fi need not sound exceptional, and that beauty is in the eyes of the beholder, sonically and aesthetically.....

DIN 45500; I'd like to know what it actually says.

DIN 45500 has defined a standard in the early days of HiFi, so that people could have some confidence in that particular gear. It is a low level standard, and IMHO it is of less interest for years.

The DIN norm for studio equipment sets tolerances much closer.

Dual 130B woofers in an exponential bass horn, 175 DLH high frequency driver, N1200 crossover.

Hi-Fi in 1952, but not today....

Hi Peter,

Do you know the DIN standard number for that one, please, for reference?

Hello Zilch,

For a long time before there was the DIN (Deutsche Industrie Norm) has the IRT (Institut for radiotechnology) the requirements of the studio equipment in the so-called “brown book” specified. Here you find some unfortunately only into German

ps. sorry for my bad english

Zilch,

sorry for the delay, I missed to look up here.

In Germany all and everything has a norm. These are made and SOLD by
http://www.normung.din.de/index.php?...&na_id=normung
[You only have to care when you are commercially affected - breathing is not yet normed, I suppose]

I have found a short overview (Telefunken Tonband Taschenbuch, 1966). Many items seem to explain out of context, let me know if I should translate.

Specific devices in broadcasting studios have their own specifications defined by "Brown Books" as mentioned by Juergen. International norms have been important too (CCIR, NARTB).
